Technical Requirements Rau Roj Immersed Transformers
Apr 12, 2024
Tso lus
1. Roj immersed transformer lub cev: Lub high-voltage winding yog mob nrog tooj liab hlau, thiab cov low-voltage winding yog mob nrog tooj liab ntawv ci. Lub coil txais cov iav fiber ntau imported epoxy resin tag nrho lub tshuab nqus tsev txhaj tshuaj, nrog lub zog nruj heev thiab lub zog txhua yam, zoo luv Circuit Court kuj, thiab sib npaug ampere tig rau siab thiab qis voltage coils. Lub epoxy resin iav fiber ntau sib xyaw muaj tib lub thermal expansion coefficient raws li tus neeg xyuas pib tooj liab, kom ntseeg tau tias lub kauj tsis tawg. Muaj zog cua kub dissipation kev ua tau zoo. Txhim kho qhov ntsuas kub thiab tswj qhov system kom pom qhov ntsuas kub ntawm peb-theem winding ntawm lub transformer. Thaum qhov ntsuas kub tsawg, lub ntsuas kub tuaj yeem xa cov teeb liab los tswj qhov pib / nres, tshaj qhov ntsuas kub, thiab kev tiv thaiv ntawm tus kiv cua. Ob khub ntawm passive hu yog muab rau cia li pib tus kiv cua ntawm lub substation. Cov tub ntxhais hlau thiab tag nrho cov khoom siv hlau raug yuav tsum tau txais kev tiv thaiv xeb. Lub nameplate yog ua los ntawm stainless hlau, thiab cov ntaub ntawv tseem ceeb hais txog lub transformer yog cim rau ntawm lub nameplate raws li tus qauv. Lub plhaub yog sib sau ua ke ntawm qhov chaw thiab ua los ntawm stainless hlau phaj. Nws muaj kev sib txuas lus 485 interface thiab tuaj yeem xa cov xwm txheej ua haujlwm ntawm lub tshuab hloov pauv.
2. Covroj immersed transformerua haujlwm nrog kev thauj khoom thiab tsis pub tshaj qhov kub thaum lub kiv cua tsis khiav; Nyob rau hauv ib txwm ua haujlwm ntawm tus kiv cua, nws raug tso cai ua haujlwm nrog kev ua haujlwm dhau ntawm 50%, yam tsis muaj cua sov, ceeb toom, lossis tawm mus.
3. Roj immersed transformer tsis muaj load poob: Qhov tsis muaj-load poob yuav tsum raug tsim raws li tus qauv tsis zoo, thiab yuav tsum tsis yog qhov yuam kev zoo. Nws yuav tsum ua raws li tus qauv siv tshiab ntawm Shandong Electric Power Company.
4. Kev ntsuas suab nrov: Thaum lub kiv cua tsis ua haujlwm ib txwm, 2000KVA transformer qis dua 52ab.
5. Creepage tshwj xeeb nrug: Organic khoom tsis tsawg tshaj 20mmKV, ceramic tsis tsawg tshaj 18mm / KVo20, high-voltage sab theem rau hauv av thiab theem rau theem huv si huab cua kev nyab xeeb net nrug (nyob ib feem) 2125mo
6. Lub high-voltage incoming kab yog ib txoj kab uas ua tau raws li cov kev xav tau ntawm cov kab sab saud lossis sab saud; Cov kab hluav taws xob uas tsis tshua muaj hluav taws xob yog cov kab hluav taws xob busbar, nrog cov kab tawm sab saud.
7. Yuav tsum muaj lub qhov rooj nkag thiab qhov rais nyob rau pem hauv ntej thiab nram qab ntawm lub txee kom yooj yim tshuaj xyuas ntawm ntau yam pob qij txha.
8. Nruab nrog lub ntsuas kub thiab nruab nrog lub thawv ntsuas kub; Cov microswitches hauv lub thawv tswj yuav tsum raug muab los ntawm cov chaw tsim khoom. Tag nrho cov khoom yuav tsum tau siv cov khoom siv rwb thaiv tsev uas tau txheeb xyuas los ntawm "ob ntu".
9. Lub dav hlau hauv av (10cm) yuav tsum ntws tawm ntawm qhov chaw tsim nyog, thiab cov seem yuav tsum tau pleev xim rau cov xim xim sib xws.
10. Nyob rau hauv ib txwm ua hauj lwm thiab load tej yam kev mob, kev khiav hauj lwm lub neej ntawm lub transformer yog 30 xyoo.
